Providing a major twist, given Dexter and Deb never mentioned having another sibling who passed throughoutDexter’s original eight seasons,Dexter: Original Sin’s premiere reveals they had an older brother who died as a child. After Dexter and Deb come home from the college party, Harry has a flashback to what appears to be the fall of 1972 or early 1973, about a year before he adopted Dexter. In the flashback, a younger Harry is watching a Miami Dolphins football game while calling to his son, Junior, who suddenly stops responding to him in the backyard.

The flashback then cuts to Harry’s wife, Doris, returning home to see Junior’s body being carted away by a coroner, with Doris screaming while Harry tries to comfort her.

Not only is this revelation that Harry had another son before Dexter a huge shock, but it also begs the question whether Dexter and Deb even knew about their brother.Junior died a year before Dexter’s adoption and a couple of years before Deb was born, so it’s possible that Harry and Doris’ grief led them to avoid ever mentioning their dead son again – especially given the guilt that Harry harbors for not being able to save him. Tying into that grief, the backstory of Junior Morgan’s death expands on Harry’s reason for taking Dexter in as a child.

Junior’s Death Adds Another Tragic Reason For Harry Adopting Dexter In The First Place

Harry Thought Saving Dexter Would Redeem His Failure With Junior

The originalDextershow revealed thatthree-year-old Dexter was adopted by Detective Harry Morgan in 1973 when he was found in a pool of his mother’s blood. Harry had been one of the responding officers on the scene, as Dexter’s mother, Laura Moser, had been brutally murdered in front of her sons by Hector Estrada, a drug lord who discovered that Laura had become an informant to the police. Of course, the police officer she had been sharing information with was none other than Harry Morgan, who she was also having an affair with.

We Already Know 6 Kills That Will Be In Dexter Morgan’s Prequel Show

Dexter: Original Sin will show Dexter’s earliest kills, but the franchise has already revealed six of his earliest victims and how he killed them.

Therefore, the original show suggests that a significant reason for Harry adopting Dexter was out of guilt.Since Laura had been an informant for him, Harry felt responsible for her death, so he adopted her younger son Dexterwhile leaving her elder son,Brian Moser (the future Ice Truck Killer), to be placed in a psychiatric hospital. It was also implied that Harry and Doris adopted Dexter because Harry felt responsible for the boy after finding and rescuing him, and because the Morgans didn’t have any children of their own.

While he couldn’t save Junior, Harry could save Dexter.

However, the revelation of Junior’s death adds another reason to Harry’s decision to adopt Dexter and raise him.By adopting Dexter as his son, Harry felt like he had another chance to redeem himself after Junior’s death. While he couldn’t save Junior, Harry could save Dexter. Dexter would give Harry and Doris another chance at raising the son that they lost, and Harry could continue to “save” him by trying to preventDexter’s Dark Passengerfrom turning him into Brian, who he felt was already too far gone, through the Code of Harry.

Junior’s Fate Makes Harry’s Death Before Dexter Even More Upsetting

Harry’s Guilt Over Failing Both Of His Sons Was Too Overbearing

One of the biggest surprise reveals inDexter’s original series involved the truth behind Harry Morgan’s death. While Dexter and Deb were told that their father died from heart disease, they eventuallylearned in season 2 that Harry died by suicide. After seeing Dexter dismember one of his victims, Harry fatally overdosed on his heart medication, being wracked with guilt over teaching Dexter the Code and guiding his son into becoming a serial killer. While seeing Dexter in the act of his killing incited Harry’s death, the backstory with Junior adds another tragic layer to his fate.

Based on Dexter’s voiceover narration, Harry Morgan dies approximately one year afterDexter: Original Sin’s premiere.

When seeingDexter operate as the Bay Harbor Butcher, Harry decided that he failed both his sons. Not only had he been unable to save Junior from drowning as a child, but he had also turned his other son into a “monster” by allowing him to kill and butcher people.Harry couldn’t live with his perceived guilt of being responsible for both of his sons’ demisesand his death tragically soon followed. It seems that was his solution to attempt to ensure he didn’t “ruin” Deb as well, with Harry’s death haunting his children long afterDexter: Original Sin’s timeline.
